Compact high capacity 7.4v Ultra Graphene battery pack. Perfect for P-Limited FE boat racing. Built with fat 10 AWG wire to help kick up your boats performance. Not recommended for high amp load open P class racing, but perfect for 4S P limited boats. 2S 2P offers more capacity than out long pack 6000 2S in a compact package. I have seen super low IR numbers and great performance out of my test packs.
